We have been installing Google apps for many of our customers as part of our website marketing package. Many businesses like the idea of having their email, calendar, documents from their business with them on their Smartphone. I don't know how I would be able to work without it. We have had allot of questions on how to add Gmail to your Android phone or smart phone. While we can't show each type of cell phone here. I found an easy demo of how to add Gmail to an android Smartphone through T-Mobile that could be helpful to you. Using other phone applications should be similar in most cases. If you are not sure ask your local cell phone service provider before making any changes to your phone. Take a look at this video to see if it can help you to add Gmail to your Smartphone. Let me know how it works for you.
